Thread-topic: [Xen-devel] [PATCH] Integrating applications into Mini-OS
This seems like a really good idea. I have been meaning to fix
VIRT_START. I see your patch shows
-#define VIRT_START              0xFFFFFFFF00000000UL
I remember changing this to 0xFFFFFFFF80000000UL. Are you diffing
against the latest changeset? Could you please check if this works on
x86_64 too?
